Cheesy Beef Spirals

This was an easy-to-assemble casserole. It was very good with garlic toast. Trevor loved it!

2 cups uncooked spiral pasta
2 pounds ground beef
2 small onions, chopped (use to your liking)
1 garlic clove, minced
1 jar (26 ounces) spaghetti sauce
1 jar (4-1/2 ounces) sliced mushrooms, drained
1/2 cup sour cream
1/2 pound process cheese (Velveeta), cubed
2 cups (8 ounces) shredded part-skim mozzarella cheese

Cook pasta according to package directions. Meanwhile, in a large saucepan, cook the beef, onions and garlic over medium heat until meat is no longer pink; drain. Stir in spaghetti sauce and mushrooms; bring to a boil. Reduce heat; cover and simmer for 20 minutes.

Place 1/2 cup of meat sauce in a greased shallow 2-1/2 qt. baking dish. Drain pasta; place half over sauce. Top with half of the remaining meat sauce; spread with sour cream. Top with process cheese and remaining pasta and meat sauce. Sprinkle with mozzarella cheese.

Cover and bake at 350 for 30 minutes. Uncover; bake 10 minutes longer.
